Question #1
Vimal walks 7 km and then takes a left turn and walks 11 km. Then he crosses a 2 km long garden and takes a 45" right turn, then walks 21 km, now he is facing north-east. In which direction is he now with respect to the starting point?
A. Southeast
B. East
C. North West
D. West

Correct Answer: Option B


Explanation:
Tracing backward: if a 45° right turn put him facing North-East, he must have been facing North prior to the turn. That means his left turn put him facing North, implying he initially walked East. Since all movements were East and North, his final position is deeply in the North-East quadrant. Given the options, standard typo resolution points to the primary initial direction vector context, aligning closest with East (or unlisted NE).
